Haha even those physics are abit erratic, she's only kneeling down & yet her bum ripples like a soft gust of wind tickling a calm ocean. Personally if they were going to make the characters backsides wobble like prodded jelly then they would have to add that same feature to the fellows as well just so it looked abit more natural. Wouldn't look right having the blokes with a lifeless arse while just the females have jiggling pert bottoms. Imo, if we want life in the backsides, give it to all genders. I also want beard physics to go with the rear movements! Imagine Tengu clunking around on his stilts as his corroded old crusty clacker shakes about & his withered beard rustles in the breeze as he hovers around like a hard to raid blowy at your fly screen. Hell yeah!
Nerf those Rob Zombies for the Teng & the Gen of the Fu variety.
I like some of the ideas for Phase 4 stage too! I'd like a clinically clean underground lab with strobing lights reflecting off polished, heaven-white floors, bald naked clones floating in green, bubbling fluorescent tubes, yellow biohazard suits dangling from walls & glass cabinets filled with flammable chemicals that gradually burn the lab if you pummel your opponent into them. Another stage I'd like for her is something abit more industrial. Maybe an underground blast furnace with clanging pipes, hissing valves, thunking cog-worked gears & steaming pistons. When you throw your opponent into a nearby whirring turbine it could cause the place to collapse while the players dodge the falling masonry similar to how the coconuts fall from the tree in Zack's island.
Anyway just putting an idea out there.
